Abstract (en)
[origin: US5015731A] Copper complex formazan compounds which have fiber-reactive properties and are very highly suitable for use as dyes for dyeing carboxamido-containing and/or hydroxy-containing material, such as fiber material, for example wool and cellulose fiber materials, have the general formula (1) <IMAGE> (1) D(SO2Y)k where A is a benzene or naphthylene ring which may be substituted by substituents customary in dyes, such as halogen, nitro, alkyl and alkoxy, B is alkylene of 1 to 8 carbon atoms or alkenylene of 2 to 8 carbon atoms which may each be substituted by phenyl which in turn may contain the substituents customary in dyes, or is alkylene-phenylene or alkenylene-phenylene having lower alkylene and alkenylene radicals, while the phenylene radicals may in turn contain the substituents customary in dyes, or is a phenylene or naphthylene radical which may contain substituents customary in dyes, or is the bivalent radical of a heterocycle, such as furan, thiophene or benzimidazole, or -B-Z together is hydrogen, Z is a water-solubilizing group, such as sulfo, k is 1 or 2, m is 0, 1 or 2, n is 0, 1 or 2, the sum (m+n) is 1 to 4; X is oxygen or carbonyloxy, R is hydrogen or substituted or unsubstituted lower alkyl, D is substituted or unsubstituted phenylene or naphthylene, Y is vinyl or an ethyl group which contains in the beta -position a substituent which is eliminatable under alkaline conditions, and M is hydrogen, an alkali metal or an alkaline earth metal.
